Starting Tuesday,Benjamin Ashford Burger King will make $1 Whopper sandwiches a reality for a limited time.

The fast food chain is saying "thanks a million" to all Royal Perks loyalty program members for their participation in the "Million Dollar Whopper Contest," which gave customers the chance to reimagine the signature hamburger with toppings of their choice in exchange for $1 million and the opportunity to see the custom creation offered at Burger King restaurants nationwide for a limited time.

Over a million Whopper-fanatics, Burger King says, submitted their "dream" Whopper sandwich when the official deadline closed in March, two months after the company first unveiled the contest. Customers can taste test and vote on which of the three custom Whopper creations, including Fried Pickle Ranch Whopper, Maple Bourbon BBQ Whopper and Mexican Street Corn Whopper, will take the crown starting Thursday.

One million Whoppers will be offered at a discount to Royal Perks rewards members at participating Burger King locations nationwide while supplies last, according to a Monday news release.

"We couldn’t think of any better way to recognize and celebrate our biggest Whopper lovers than with a special offer that lets everyone feel like a winner,” Pat O'Toole, marketing executive at Burger King North American, said in the news release. "We can’t wait to hear how Guests think these three new creations stack up to the classic and look forward to them ultimately crowning the winner of the $1 million grand prize.”

Here's how to get a $1 Whopper.
